This bug crops up from time to time and cause fasmw to crash, It happens in the save dialog, when this crash happens the filename in the 'filename:' text box is trashed, then sooner rather than later fasmw will crash. The crash dump below should help in solving this mystery.

Code:

maybe it caused because you have spaces in path?

All I can say from this dump is that editor tried to release the memory block associated with control (for what reason? it should happen to be called only on WM_DESTROY), while this block of memory was already released/bad. Well, it's also possible that due to some stack error this procedure was jumped to, and this would explain the bad data. Is it possible you'd recall at least few final operations that caused this crash?

Well I found where my post went Smile . I did forget to mention that I had multiple files open. I did hit the F9 key to rerun a program, and because fasmw saves all files before running and app, the save dialog came up, and the filename was trashed, each time I selected the save dialog menuitem, the filname came up trashed. When I clicked the close button, that's when it crashed. If this happens again, I'll take a screen snap shot and post it. Fortunately it doesn't happen too often.

If you could find out how to reproduce the bug, this would be the best help in finding it out. But it might be also related to what OS you're running it on. On my XP the fasmw with rewritten asmedit control has never crashed yet.

I can't repoduce the bug, at least I haven't been able to yet. By the way I'm using windows xp sp2. I won't post this problem again unless I can reproduce the crash.
